NON SLAM CHECK VALVE WAFER TYPE
“aline” Make Non Slam Check Valve – Wafer Type is designed to prevent reverse flow in pipelines while eliminating the water hammer effect caused by sudden flow reversal. Engineered with a spring-assisted disc mechanism, the valve closes instantly before reverse flow occurs, ensuring smooth operation and protecting pumps, compressors, and piping systems from pressure surges and mechanical damage.
Its compact wafer design allows easy installation between standard pipeline flanges, reducing space requirements and overall system weight. Manufactured from premium-grade materials with precision machining, the valve offers low pressure drop, excellent sealing performance, corrosion resistance, and long service life. The spring-loaded mechanism ensures reliable operation in both horizontal and vertical installations.
ALINE Non Slam Check Valves are widely used in Water Treatment Plants, HVAC Systems, Pumping Stations, Chemical Industries, Oil & Gas, Power Plants, Pharmaceutical Industries, Food Processing, Fire Fighting Systems, Marine Applications, and General Industrial Process Pipelines where dependable non-return flow protection is essential.
Built for durability and maintenance-free performance, the ALINE Non Slam Check Valve provides superior protection against backflow while improving the reliability and efficiency of industrial fluid handling systems.
